The processor for supporting the mobile TV may process media data that complies with standards of, for example, digital multimedia broadcasting (DMB), digital video broadcasting (DVB), or media flow.

FIG. 3 is a perspective view illustrating a wearable electronic device according to various embodiments of the present disclosure.

FIG. 4 is a perspective view illustrating a wearable electronic device according to various embodiments of the present disclosure which is viewed from another direction according to the related art.

Referring to FIGS. 3 and 4, according to various embodiments of the present disclosure, a wearable electronic device 100 (e.g., the electronic device 10 or 20) includes a main body 101 and a wearing unit 102. The wearing unit 102 may include a first wearing member 121 a, a binding member 123, and a driving member 127. The binding member 123 is coupled to the first wearing member 121 a and is movable in the longitudinal direction of the first wearing member 121 a, and the driving member 127 may move the binding member 123 in a direction where the length of the wearing unit 102 is reduced.

The main body 101 includes various circuit devices, such as an AP, a communication circuit, and a memory device, equipped therein, and a display device 111 mounted on the front surface thereof. On any one surface of the main body 101, for example, on the rear surface, various sensors, for example, biometric signal sensors 113 (e.g., the biometric sensor 24I), and on the front surface (not illustrated), for example, an illumination sensor, may be disposed. The biometric signal sensors 113 are installed to protrude from the rear surface of the main body 101 so that the biometric signal sensors 113 may be more stably in close contact with the user's body. The biometric signal sensors 113 may detect at least one of information items related to the user's health condition, for example, blood pressure, electrocardiogram, HRV, heart rate monitor (HRM), photo plethysmo graph (PPG), sleeping section, skin temperature, heart rate, blood flow, blood sugar, oxygen saturation, pulse wave, and electrocardiogram (ECG).

The wearing unit 102 is provided for allowing the main body 101 to be worn on the user's body, and the first wearing member 121 a may extend in one direction from the main body 101. In addition, the wearing unit 102 may further include a second wearing member 121 b from the main body 101 in a direction away from the first wearing member 121 a. The first and second wearing members 121 a and 121 b may be implemented as a structure of a band or a watch chain. A binding member 123 may be provided on the first wearing member 121 a to be selectively bound to the second wearing member 121 b. In the second wearing member 121 b, a plurality of binding holes 125 are arranged in the longitudinal direction, and a portion of the binding member 123 is engaged with and bound to at least one of the binding holes 125. The wearing unit 102 maintains a closed curve shape in the state where the binding member 123 is bound with the second wearing member 121 b so that the main body 101 may be stably worn on the user's body (e.g., wrist).

The binding member 123 is provided to bind the first wearing member 121 a and the second wearing member 121 b, in which the binding member 123 may be coupled to the first wearing member 121 a to be movable in the longitudinal direction of the first wearing member 121 a. As the binding member 123 moves, the length of the wearing unit 102 may be reduced. In the state where the user wears the electronic device 100 (in the state where the binding member 123 binds the first and second wearing members 121 a and 121 b), when the length of the wearing unit 102 is reduced, the rear surface of the main body 101, for example, the biometric signal sensors 113 may be brought into more close contact with the user's body.

The binding member 123 may include a moving part 123 a coupled to at least partially wrap the first wearing member 121 a, and a binding part 123 b mounted on the moving part 123 a to be selectively bound with the second wearing member 121 b. The moving part 123 a may be installed on an end portion of the first wearing member 121 a to be movable in the longitudinal direction of the first wearing member 121 a. For example, the end portion of the first wearing member 121 a may provide a rail function that guides the movement of the moving part 123 a. The binding part 123 b may include a protrusion or a pin to be engaged with the binding holes 125, and also provide a holder function that brings a portion of the second wearing member 121 b into close contact with the first wearing member 121 a.

The driving member 127 may be accommodated in the first wearing member 121 a, and may move the binding member 123 in a direction of reducing the length of the wearing unit 102. The driving member 127 may include a wire 127 b fabricated using an artificial muscle, a shape memory alloy, an EAP. When the wire 127 b is contracted by receiving an electric signal, the binding member 123 may be moved. The structure and arrangement of the driving member 127 will be described in more detail with reference to FIGS. 5 to 8.

FIG. 5 is a view for illustrating a structure of a wearing unit of a wearable electronic device according to one of various embodiments of the present disclosure.

FIG. 6 is a view for illustrating a variation of a structure of the wearing unit of a wearable electronic device according to one of various embodiments of the present disclosure.

Referring to FIGS. 5 and 6, the main body 101 may be brought into close contact with the user's body by reducing the length of the wearing unit 102 as necessary (for detecting a biometric signal) while the wearing unit 102 is worn to be comfortable to the user. When the length of the wearing unit 102 is reduced by about 10 mm, the main body 101 may be brought into close contact with the user's wrist in the state where the electronic device 100 is worn on the wrist such that the user does not feel pressure on the user's body. The wire 127 made of, for example, an artificial muscle, a shape memory alloy, or an EAP may be contracted by about 3 to 5% of the entire length when a driving signal of 9V, 400 mA (3.6 W) is applied thereto although the amount of contraction may slightly differ depending on the material. For example, in the case where the driving member is formed using a wire made of a shape memory alloy and has a length of about 400 mm, a displacement amount of about 12.5 mm in length may be obtained when an electric signal (e.g., a driving signal of 9V, 400 mA (3.6 W)) is applied thereto. For example, the driving member may move the binding member 123 by about 10 mm by using the wire 127 b made of the shape memory alloy having a length of 400 mm.

Assuming that the user's wrist is about 200 mm around, it is estimated that the first wearing member 121 a is fabricated to have a length of about 100 mm. In order to dispose the wire having a length of about 400 mm in the first wearing member 121 a having a length of about 100 mm, the wire 127 b may be disposed in a vortex shape according the related art in FIG. 5 or a zigzag shape according to the related art in FIG. 6. The driving member 127, for example, one end of the wire 127 b may be fixed to the inside of the main body 101 or the first wearing member 121 a, and the other end may be fixed to the binding member 123. A conductive line 127 c may be further disposed within the first wearing member 121 a in order to apply an electric signal by connecting an electrode to each end of the wire 127 b.

The driving member 127 may include a tube 127 a. When the wire 127 b is contracted in the state where the wire 127 b is arranged in the vortex shape or zigzag shape, the diameter of the vortex shape may be reduced or the intervals of the zigzag may be changed. When the arrangement shape of the wire 127 b is changed due to the contraction of the wire 127 b, the binding member 123 may not be moved by the displacement of the wire 127 b. Accordingly, it is possible to suppress the arrangement shape of the wire 127 b from being changed by arranging the wire 127 b within the tube 127 a, and to convert the displacement of the wire 127 b into the movement of the binding member 123. Then, the tube 127 a may maintain the arrangement shape of the wire 127 b while maintaining the flexibility of the first wearing member 121 a.

FIG. 7 is a view for illustrating a structure of a driving member of a wearable electronic device according to various embodiments of the present disclosure.

FIG. 8 is a view for illustrating an operating aspect of a driving member of a wearable electronic device according to various embodiments of the present disclosure.

Referring to FIGS. 7 and 8, the first wearing member 121 a may include a fixing plate 121 c provided at an end thereof. The binding member 123 may move in the longitudinal direction of the first wearing member 121 a, for example, in the state where the moving part 123 a wraps the fixing plate 121 c. The driving member 127, for example, the tube 127 a may be fixed to the fixing plate 121 c while being arranged within the first wearing member 121 a. The wire 127 b may further extend to the outside of the fixing plate 121 c from the one end of the tube 127 a so that the end may be bound and fixed to the binding member 123, for example, the moving part 123 a. It is noted that, for example, the conductive line for applying an electric signal to the wire 127 b is omitted in FIGS. 7 and 8 for the purpose of concise illustration of the drawings.

When the electric signal is applied to the driving member 127, the wire 127 b is contracted to move the binding member 123 in the direction where the fixing plate 121 c is further accommodated as illustrated in FIG. 8. As the binding member 123 moves, the length of the wearing unit 102 is gradually reduced, and the main body 101, for example, the biometric signal sensors 113 may come in closer contact with the user's body. When the electric signal applied to the driving member 127 is cut off, the binding member 123 is returned to the position according to the related art in FIG. 6 by the reaction force applied by the user's body, and the wearing unit may be gradually expanded. Although not illustrated, in order to return the binding member 123 to the position according to the related art in FIG. 7, for example, a bias spring may be further arranged.

Meanwhile, even if the tube 127 a is made of a material capable of maintaining the flexibility of the first wearing member 121 a, it is unavoidable that the flexibility of the first wearing member 121 a may be degraded compared with the wearing member in which the tube 127 a is not arranged. In addition, when the tube 127 a is arranged in the vortex shape or the zigzag shape so that its length is increased, the flexibility of the first wearing member 121 a may further degraded.

According to various embodiments of the present disclosure, the electronic device 100 may further include an intermediate member that increase the displacement of the driving member 127, for example, the wire 127 b to move the binding member 123. By arranging the intermediate member, the length of the wire 127 b provided in the first wearing member 121 a, and hence, the length of the tube 127 a may be reduced. A structure of the intermediate member will be described with reference to FIGS. 9 to 13.

FIG. 9 is a view for illustrating an intermediate member of the wearable electronic device according to various embodiments of the present disclosure.

Referring to FIG. 9, the wire driving member 127, made of any one of, e.g., an artificial muscle, a shape memory alloy, and an electro-active polymer, may be connected to the binding member 123, for example, the moving part 123 a, through an intermediate member 129. The intermediate member 129 is operated by the contraction of the wire 127 b, and the binding member 123 may be moved by increasing the displacement of the wire 127 b. The wire 127 b is arranged within the first wearing member 121 a in the state where the wire 127 b is accommodated in the tube 127 a, and may receive an electric signal applied through the conductive lines 127 c. In order to arrange the intermediate member 129, the first wearing member 121 a may include a fixing plate 121 c provided at an end thereof. The binding member 123 may include a moving part 123 a coupled to wrap at least a portion of the first wearing member 121 a, for example, the fixing plate 121 c, and the moving part 123 a may be moved in the longitudinal direction of the first wearing member 121 a by being guided by the fixing plate 121 c. The binding member 123 may include a binding part 123 c having a buckle structure bound with the second wearing member 121 b.

The intermediate member 129 may include at least one link. For example, the intermediate member 129 may be implemented as a link assembly. The link may connect the driving member 127, for example, the wire 127 b, and the binding member 123 with each other, and increase the displacement of the wire 127 b so as to move the binding member 123. The intermediate member 129 may be implemented by a single link.

FIG. 9 further exemplifies a configuration in which each of a pair of links is pivotally coupled to the fixing plate 121 c.

One end of the driving member 127, for example, one end of the wire 127 b is fixed to the inside of the first wearing member 121 a, the other end is connected to a first point P1 of a first link 129 a to pivot the first link 129 a. A second point P2 of the first link 129 a may be connected to the binding member 123 via a second link 129 b among the links. In setting the first and second points P1 and P2, the first point P1 may be located closer to the pivot axis A1 of the first link 129 a than the second point P2. Through the arrangement of the first and second points P1 and P2 and the pivot axis A1, the displacement of the wire 127 b is increased via the first link 129 a to pivot or move the second link 129 b or the binding member 123. For example, the displacement of the second point P2 according to the pivot of the first link 129 a is set to be larger than the displacement of the first point P1. By increasing the distance ratio from the pivot axis A1 of the first link 129 a to the first and second points P1 and P2, the moving distance of the binding member 123 in relation to the displacement of the driving member 123 may be further increased.

In the present disclosure, by additionally arranging the second link 129 b, the ratio of the moving distance of the binding member 123 in relation to the displacement of the driving member 127 may be further increased. A third point P3 of the second link 129 b may be connected to the second point P2 via a first connection link 129 c, and the fourth point P4 of the second link 129 b may be connected to the binding member 123 via a second connection link 129 d. The third point P3 may be located closer to a pivot axis A2 of the second link 129 b than a fourth point P4, and the moving distance of the binding member 123 in relation to the displacement of the driving member 127 may be further increased depending on the distance ratio from the pivot axis A2 of the second link 129 b to the third and fourth points P3 and P4.

Each of the first and second links 129 a and 129 b may be arranged in a direction substantially perpendicular to the displacement direction of the driving member 127 or the moving direction of the binding member 123. Through the arrangement of the first and second links 129 a and 129 b, the displacement of the wire 127 b may be more effectively increased. The other end of the driving member 127 may be directly connected to the first point P1. However, in the case where the driving member 127 includes a plurality of wires 127 b, the driving member 127 and the first point P1 may be connected with each other by arranging an additional connection link 129 e.

When the displacement of the second point P2 is set to about two times the displacement of the first point P1 and the displacement of the fourth point P4 is set to about five times the displacement of the third point P3, the moving distance of the binding member 123 may be increased to ten times the displacement of the wire 127 b. For example, in order to contract the wearing unit 102 about 10 mm, a displacement of about 1 mm may be required in the driving member 127. When the wire 127 b that forms the driving member 127 has a contraction rate of about 3% when an electric signal (e.g., a driving signal of 9V, 400 mA (3.6 W)) is applied thereto, the driving member 127 may be formed using the wire 127 b merely having a length of about 30 mm. However, in consideration of, for example, a manufacturing tolerance or the reaction force of, for example, the first wearing member 121 a, the driving member 127 may be formed using the wire 127 b having a length of about 40 mm. In this way, a comfortable wearing feeling may be normally provided and the main body 101 may be sufficiently in close contact with the user's body when a biometric signal is measured. In addition, since the length of the driving member 127 is sufficiently reduced, it is possible to alleviate the degradation of the flexibility of the first wearing member 121 a due to the arrangement of, for example, the tube.

FIG. 10 is a view for illustrating a variation of an intermediate member of a wearable electronic device according to various embodiments of the present disclosure.

FIG. 11 is a plan view for illustrating a variation of the intermediate member of a wearable electronic device according to various embodiments of the present disclosure.

Referring to FIGS. 10 and 11, an intermediate member 229 according to the present disclosure is a variation of the link assembly structure of the preceding embodiment. The configuration of the intermediate member 229 will be described, in which the descriptions in the preceding embodiment will be referred to the components similar or equal to those of the preceding embodiment.

The intermediate member 229 may be machined and formed in a rectangular shape. For example, a pair of first links 229 a may be arranged on a first side and a pair of second links 229 b may be arranged on a second side that is parallel to the first side. On the third and fourth sides of the intermediate member 229, first connection links 229 c are arranged so as to link the second points P2 of the first links 229 a to the third points P3 of the second links 229 b. The first points P1 of the first links 229 a may be positioned approximately at the center of the first side of the intermediate member 229 to be in contact with each other and may be connected to the wire 127 b of the driving member. The second points P2 of the first links 229 a may be respectively connected with the first connection links 229 c approximately at the corners where the first side of the intermediate member 229 is connected with the third and fourth sides. The third points P3 of the second links 229 b may be respectively connected with the first connection links 229 c approximately at the corners where the second side of the intermediate member 229 is connected with the third and fourth sides. The fourth points P4 of the second links 229 b are positioned to be in contact with each other approximately at the center of the second side of the intermediate member 229 and may be connected to the binding member through the second connection link 229 d. The second connection link 229 d may be formed of a rigid wire.

By the contraction of the wire 127 b of the driving member, the first and second links 229 a and 229 b may pivot about the pivot axes A1 and A2, respectively. With the arrangement of the first to fourth points P1, P2, P3, and P4 and the pivot axes A1 and A2, the displacement of the fourth points P4 (e.g., the moving distance of the binding member) in relation to the displacement of the first points P1 (e.g., the displacement of the wire 127 b according to the application of an electric signal) may be increased. Apart from this, the moving distance of the binding member in relation to the displacement of the wire may be increased by utilizing various link assembly structures.

FIG. 12 is a view for illustrating another variation of an intermediate member of a wearable electronic device according to various embodiments of the present disclosure.

Referring to FIG. 12. an intermediate member 329 according to the present embodiment may increase the displacement of the binding member, for example, the moving part 123 a in relation to the driving member, for example, the wire 127 b, using pulleys 329 a. The intermediate member 329 may include one or more pulleys 329 a mounted on the binding member, for example, the moving part 123 a. One end of the wire 127 b is fixed to the main body (or the first wearing member), and the other end may be fixed to the moving part 123 a and arranged via the pulley 329 a. With this arrangement, the moving distance of the moving part 123 a may be further increased compared with a real displacement of the wire 127 b. For example, in the case where one pulley 329 a is arranged, the displacement of the moving part 123 a may be increased to two times the real displacement of the wire 127 b.

The displacement of the moving part 123 a may be increased to four times the real displacement of the wire 127 b. For example, in the case where the wire 127 b made of a material that is contracted by about 3% of the entire length when an electric signal is applied thereto is used in a length of about 100 mm, and the intermediate member 329 having the pulley structure according to the related art in FIG. 12 is installed, the binding member, for example, the moving part 123 a may be moved within a range of about 12 mm.

FIG. 13 is a view for illustrating still another variation of an intermediate member of a wearable electronic device according to various embodiments of the present disclosure.

Referring to FIG. 13, an intermediate member 429 according to the present disclosure may have a structure in which a rectangular link assembly is formed with four links 429 a, and the diagonal lengths of the link assembly may be adjusted using a driving member, for example, a wire 429 b. The links 429 a may have the same length and may be coupled to pivot in relation to each other so as to form four joint portions J1, J2, J3, and J4. Among the joint portions, a first joint portion J1 may be fixed to a first wearing member 121 a, and a second joint point J2, positioned in the diagonal direction in relation to the first joint portion J1, may be fixed to the moving part 123 a of the binding member. For example, the first and second joint portions J1 and J2 may be fixed to the first wearing member 121 a and the moving part 123 a, respectively, and the links 429 a may be pivotally coupled to one of the first and second joint portions J1 and J2.

As the links 429 a pivot in relation to each other, a diagonal length of the intermediate member 429, for example, the distance between the first and second joint portions J1 and J2 may be changed to move the moving part 123 a in the longitudinal direction of the first wearing member 121 a. The wire 429 b may be contracted by receiving an electric signal applied thereto, thereby pivoting the links 429 a in relation to each other. The wire 429 b passes through one of the first and second joint portions J1 and J2, and the opposite ends of the wire 429 b may be respectively fixed adjacent to the third and fourth joint portions J3 and J4 which are diagonally positioned in relation to each other. Each of the links 429 a may include a driving arm 429 d extending from an end positioned at one of the third and fourth joint portions J3 and J4. Each of the opposite ends of the wire 429 b may be fixed to one of the driving arms 429 d. Each of the links 429 a is pivoted about one of the third and fourth joint portions J3 and J4, and the driving force generated by the contraction of the wire 429 b may act on a point (e.g., a driving arm 429 d) out of each of the pivot centers of the links 429 a (e.g., first to fourth joint portions J1, J2, J3, and J4) to pivot each of the links 429 a. Depending on the distance between the first and third joint portions J1 and J3 per the distance from the third joint portion J3 (or the fourth joint portion J4) to the point where one end of the wire 429 b is fixed, the change of the distance between the first and second joint portions J1 and J2 per the displacement of the wire 429 b may be increased. As the distance between the first and second joint portions J1 and J2 is reduced, the moving part 123 a may move on the first wearing member 121 a so as to reduce the length of the wearing unit. As the length of the wearing unit is reduced, the main body 101 may be further in close contact with the user's body, and the biometric signal sensors mounted on the main body 101 may detect the information related to the user's health condition more precisely.

The intermediate member 429 may further include bias springs 429 c. The bias springs 429 c may provide a driving force acting in a direction where the spacing between the first and second joint portions J1 and J2 is increased. For example, when an electric signal applied to the wire 429 b is cut off, the spacing between the first and second joint portions J1 and J2 may be increased again by the driving force of the bias springs 429 c. Accordingly, after the detection of a biometric signal is completed, the user may wear the electronic device comfortably in a state where the user's body is not pressed. Meanwhile, when the electric signal applied to the wire 429 b is cut off, the driving force by the wire 429 b is released so that the moving part 123 a may be returned to its original position by the reaction force applied by the user's body. For example, even if the bias springs 429 c are not provided, the spacing between the first and second joint portions J1 and J2 may be increased within a permissible range (in a range where the moving part 123 a is not out of the first wearing member 121 a) unless the electric signal is applied to the wire 429 b.

FIG. 14 is a perspective view illustrating a wearable electronic device according to various embodiments of the present disclosure.

Referring to FIG. 14, the electronic device 200 according to the present disclosure may include a main body 101 and a wearing unit 202, in which the wearing unit 202 may take a closed curve shape to be worn on the user's body. The wearing unit 202 includes a first wearing member 221 a extending from one side of the main body 101, and a second wearing member 221 b extending from the other side, in which the first and second wearing members 221 a and 221 b are bound to each other through a binding member 223 so that the wearing unit 202 may be maintained in the closed curve shape. The binding member 223 may be coupled to an end of the first wearing member 221 a to be movable in the longitudinal direction of the first wearing member 221 a.

Within the first wearing member 221 a, a driving member 227 may be accommodated. The driving member 227 may have a structure in which wires 227 a and moving members 227 b are alternately connected to each other to form a zigzag form. The wires 227 a may be made of any one of an artificial muscle, a shape memory alloy, an electro-active polymer to be contracted when an electric signal is applied thereto. The moving members 227 b may be made of a rigid material to be movable in the longitudinal direction of the first wearing member 221 a (in a case where the wearing unit 202 has a closed curve shape, in the circumferential direction of the wearing unit 202) within the first wearing member 221 a according to the contraction of the wires 227 a.

One end of the driving member 227 may be fixed to the main body 101 (or, to the inside of the first wearing member 221 a), and the other end may be fixed to the binding member 223. When an electric signal is applied to each of the wires 227 a, the wires 227 a may move the binding member 223 while being contracted. When the moving members 227 b are made of a conductive material, an electrode may be provided at each of the opposite ends of the driving member 227 so as to apply an electric signal to the wires 227 a. The moving members 227 b are movable in the longitudinal direction of the first wearing member 221 a (in a case where the wearing unit 202 has a closed curve shape, in the circumferential direction of the wearing unit 202) within the first wearing member 221 a, but the rotation of the moving members 227 b within the first wearing member 221 a may be restricted. As a result, the driving force generated by the contraction of the wires 227 a may move the binding member 223.

While the present disclosure exemplifies a structure in which the other end of the driving member 227 is fixed to the binding member 223, the other end of the driving member 227 may be fixed to the end of the first wearing member 221 a if the first wearing member 221 a is made of a contractile material. In addition, if the first wearing member 221 a is made of a contractile material, the binding member 223 may be fixed to the end of the first wearing member 221 a, and the other end of the driving member 227 may be fixed to the binding member 23. In this case, the driving force generated by the contraction of the wires 227 a may contract the first wearing member 221 a. In addition, if the second wearing member 221 b is made of a contractile material, another driving member may also be arranged within the second wearing member 221 b.

FIG. 15 is a view for illustrating still another variation of a structure of a wearing unit of a wearable electronic device according to various embodiments of the present disclosure.

Referring to FIG. 15, an electronic device 300 according to the present disclosure may adjust the curvatures of first and second wearing members 321 a and 321 b that form a wearing unit 302 so as to bring the main body 101 (or the biometric signal sensors 113 mounted on the main body 101) into close contact with the user's body. The first and second wearing members 321 a and 321 b may be made of a material capable of changing the curvature thereof when an electric signal is applied thereto, such as a shape memory alloy or an electro-active polymer, and the first and second wearing members 321 a and 321 b may form the driving member by themselves. The first and second wearing members 321 a and 321 b are in contact with a binding member 323.

According to an embodiment of the present disclosure, if the first and second wearing members 321 a and 321 b are covered by a material, such as rubber, silicon, or leather, the tactility may be improved when the wearing members are worn. When an electric signal is applied to the first and second wearing members 321 a and 321 b in the state where the user wears the electronic device 300, the curvature of the first and second wearing members 321 a and 321 b is reduced so as to press the user's body. As a result, the main body 101 (or the biometric signal sensors 113 mounted on the main body 101) may be further in close contact with the user's body.

According to various embodiments of the present disclosure, the wearable electronic device 100, 200, or 300 includes a driving member made of, for example, an artificial muscle, a shape memory alloy, or an electro-active polymer such that the length or curvature of the wearing unit may be changed. Accordingly, as necessary, the biometric signal sensors mounted on the electronic device may be brought into close contact with the user's body so that information related to the user's health condition may be detected more precisely.

Hereinafter, descriptions will be made on various operating methods of a wearable electronic device according to various embodiments of the present disclosure with reference to FIGS. 16 to 24. In describing the operating methods of the wearable electronic device, reference will be made to the above descriptions for the components or the like of the electronic device.

FIG. 16 is a flow chart illustrating one operating method of a wearable electronic device according to various embodiments of the present disclosure.

Referring to FIG. 16, according to various embodiments of the present disclosure, among methods of operating the wearable electronic device 100, a first method S100 periodically may detect and acquire a user's biometric information and display the acquired biometric information as necessary, or when the value of the detected biometric information exceeds a previously set value or a threshold, may output a warning. When the user's biometric information is periodically acquired, it is possible to check, for example, the change of the user's health condition routinely. Thus, it may be useful for a user who is interested in, for example, health care or a user who requires regular checkups and constant care of, for example, high blood pressure, glycosuria, or cardiac disorder. Here, the user's “biometric information” may include information concerning blood pressure, electrocardiogram, HRV HRM, PPG, sleeping section, skin temperature, heart rate, blood flow, blood sugar, oxygen saturation, pulse wave, or ECG.

Operation S111 for performing the first method S100 is an operation for executing an application for detecting acquiring a biometric signal, in which the application may be executed at regular time intervals according to the setting of the electronic device 100 itself or the user's setting.

According to various embodiments of the present disclosure, the application for detecting and acquiring a biometric signal may be in the state where the application is executed in the background of the electronic device 100.

Subsequently, in operation S113, the electronic device 100 may determine whether the electronic device is in a sensing period. When it is determined that a current period is the sensing period in operation S113, the electronic device 100 performs operation S115 in which the electronic device 100 may drive the driving member 127 so as to gradually reduce the length of the wearing unit 102, for example, the band so that the main body 101 comes in close contact with the user's body (e.g., wrist).

In operation S117, the electronic device 100 may detect and acquire the user's biometric information through the biometric signal sensors 113. As described above, the biometric signal sensors 113 may detect at least one of blood pressure, electrocardiogram, HRV, HRM, PPG, sleeping section, skin temperature, heart rate, blood flow, blood sugar, oxygen saturation, pulse wave, and ECG.

In addition, in operation S117, the acquired user's biometric information may be output through the electronic device 100 or transmitted to or stored in, for example, another electronic device connected with the electronic device 100, a storage medium, or a medical institution capable of being connected with the electronic device 100 through, for example, a communication network. Here, the description, “biometric information may be output” may include outputting the acquired user's biometric information by sound or displaying the acquired user's biometric information on a screen. Since the display device 111 is mounted on the electronic device 100, when the acquired user's biometric information is displayed on the screen, the information needed by the user may be confirmed.

FIGS. 19 to 21 are views illustrating exemplary outputting biometric information items measured by operating methods of a wearable electronic device according to various an embodiments of the present disclosure.

Referring to FIGS. 19 and 20, when information related to, for example, electrocardiogram is detected through the biometric signal sensors 113, the electronic device 100 may output an electrocardiogram waveform and heart rate on a screen. Based on the detected biometric information, for example, blood pressure, electrocardiogram, skin temperature, and oxygen saturation, the electronic device 100 may calculate and output the user's stress index through the display device 111.

Referring to FIG. 21, when the biometric signal sensor 113 detects the user's HRM signal, the electronic device 100 may display the detected information in the combined form of a graph and text on the display device 111.

According to various embodiments, when the electronic device 100 has normally stored information related to the user's health condition, the user's current health condition may be determined by comparing the normally stored information with the detected biometric information. Apart from this, the electronic device 100 may directly output other acquired biometric information on the display device 111, or combine the stored data and the acquired data and provide, for example, a recommendation option for the user's health care to the user, as illustrated in FIGS. 19 and 21.

According to various embodiments of the present disclosure, the first method S100 may further include operation S119 of determining whether the value of the detected biometric information exceeds a pre-set value or a typically recommended threshold. In operation S119, when the value of the detected biometric information is within the threshold, the electronic device 100 may repeatedly perform the above-described operations from operation S111 of determining whether it is the sensing period again.

In operation S119, when the value of the detected biometric information exceeds the threshold, for example, when, for example, a possibility of a heart attack or an abnormal change of blood pressure is determined based on the value of the detected biometric information, the electronic device may output a warning in operation S121. The electronic device 100 may output the warning, for example, by outputting sounds or flickering the screen so as to make the user recognize that the user's health condition is abnormal. In operation S121, the electronic device 100 may output the information related to the user's health condition in various forms, in addition to outputting an acoustic (e.g., sound) or visual (e.g., screen) alarm through the speaker or the display device 111 equipped therein. For example, when it is determined as an emergency situation of, for example, a heart attack through the detected biometric information, the electronic device 100 may transmit an aid request signal including the user's personal information, positional information, and acquired biometric information. The aid request signal may be transmitted to, for example, another electronic device designated by the user of the electronic device 100, another arbitrary electronic device near the electronic device 100, or a medical institute or a first-aid medical center that may be connected via various communication networks.

According to various embodiments of the present disclosure, in the case where both the user of the electronic device that sends, for example, the aid request signal and the user of the electronic device that receives the aid request signal have permitted the transmission/reception of the aid request signal according to the emergency situation, the aid request signal may be transmitted to another arbitrary user's electronic device.

When a series of the operations as described above are completed, the electronic device 100 may releases the tightened state of the wearing unit 102 (e.g., band) so as to provide a comfortable wearing feeling to the user.

According to various embodiments of the present disclosure, based on the acquired user's biometric information, when it is determined that the user's biometric value is in the emergency situation, the electronic device 100 may detect continuously or at more rapid cycles the user's biometric information, and store or transmit the biometric information, to, for example, a medical institute or a first-aid medical center while maintaining the tightened state of the wearing unit 102.

FIG. 17 is a flow chart illustrating another operating method of a wearable electronic device according to various embodiments of the present disclosure.

Referring to FIG. 17, among methods for operating wearable electronic device 100 according to various embodiments of the present disclosure, the second method S200 is related to calculating, for example, an exercise amount when an unusual sudden change in the user's activity is determined, for example, when the user exercises.

In executing the second method S200, in operation S211, the electronic device 100 may determine whether the user exercises. When the user exercises in the state where the user wears the electronic device 100, a sudden movement of the electronic device 100 may be determined through, for example, a 6-axis sensor. The electronic device 100 may such a sudden movement as an exercise status.

In operation S211, when the exercise status is determined, the electronic device 100 drives the driving member 127 to reduce the length (or curvature) of the wearing unit 102 so that the main body 101 may come in close contact with the user's body in operation S213. As the main body 101 comes in close contact with the user's body, the biometric signal sensors 113 also may come in close contact with the user's body so as to detect a change in the user's biometric information.

In operation S215, while the user is exercising, the electronic device 100 may continuously detect a change in the user's biometric information, such as heart rate and blood pressure, through the biometric signal sensors 113. Based on the detected change in the biometric information, the electronic device 100 may calculate, for example, the user's exercise amount and consumed calories. In addition, the electronic device may quantify and store the user's exercise amount as data by, for example, the user's moving distance and time through, for example, the GPS module. For example, the electronic device 100 may not only calculate the exercise amount from the change in biometric information which is detected by the biometric signal sensors 113, but also acquire information required for calculating the user's exercise amount even through other sensors mounted on the electronic device 100.

In operation S215, for example, the calculated exercise amount may be output as a screen, and may be stored in, for example, a storage medium or any other electronic device or server accessible through a communication network. For example, a personal user may store the exercise amount in the electronic device 100 itself, and may store the exercise amount in, for example, any other storage medium as needed. In the case of a user who requires daily management of, for example, the exercise amount, for example, a sportsman, the calculated exercise amount information or the like may be transmitted to, for example, a manager's electronic device.

FIG. 22 is a view illustrating exemplary outputting biometric information items measured by operating methods of a wearable electronic device according to various an embodiments of the present disclosure.

Referring to FIG. 22, the electronic device 100 may classify the user's exercise amount information accumulated for a predetermined period by dating (or day of the week) and outputs the user's exercise amount information in the form of a graph through the display device 111. Of course, similarly to the preceding embodiments, for example, the user's exercise amount information may be output in various forms, such as a text form, through the display device 111.

According to various embodiments of the present disclosure, a person who manages a plurality of sportsmen may let each sportsman wear the electronic device 100 while he or she is taking exercise so as to calculate, for example, the exercise amount information. The manager may utilize data prepared by collecting, synthesizing, and analyzing, for example, the calculated exercise amount information by dating and each sportsman so as to plan, for example, future training strategies of each sportsman.

While the above-mentioned process for executing the second method S200 is progressing, or after, for example, the exercise amount information is output, the electronic device 100 may determine whether the user terminates the exercise in operation S217. For example, when the movement of the electronic device 100 determined from, for example, the 60-axis sensor, is slowed down or stopped, the electronic device 100 may recognize that the exercise is terminated and may stop the detection of the biometric information for calculating, for example, the exercise amount.

Operation S219 is an operation for releasing the tightened state of a band, for example, the wearing unit 102 so as to provide a comfortable wearing feeling to the user when the electronic device 100 recognizes that the exercise is terminated. In operation S219, the electronic device 100 may stop the driving of the driving member 127 to loosen the wearing unit 102, thereby providing the comfortable wearing feeling to the user.

FIG. 18 is a flow chart illustrating still another operating method of a wearable electronic device according to various embodiments of the present disclosure.

Referring to FIG. 18, among the methods of operating the electronic device 100, according to the third method S300, the user may operate the electronic device 100 as needed so as to acquire the user's biometric information or biometric information of another person who wears the electronic device 100.

In executing the third method S300, operation S311 is an operation for receiving the user's input. For example, the user may activate an application utilized for acquiring biometric information in the electronic device 100 or may operate, for example, a key provided on the electronic device 100. The electronic device 100 may receive the user's input for obtaining the biometric information from the activation of the application or the key operation.

The electronic device 100 may execute the application corresponding to the user's input in operation S313. The application executed in operation S313 may control a series of processes for acquiring the user's biometric information. For example, in operation S315, the application may make the electronic device 100 drive the driving member 127. As the driving member 127 is driven, the length of a band, for example, the wearing unit 102 is reduced so as to bring the main body 101 into close contact with the user's body.

Operation S317 is an operation for acquiring the user's biometric information. In the state where the main body 101 is in close contact with the user's body, the biometric signal sensors 113 may detect biometric information such as blood pressure and heart rate. The electronic device 100, for example, the executed application may output or separately store the user's detected biometric information in operation S319.

Operation S319 is an operation for outputting (or storing) the detected biometric information. In the case of biometric information that may be detected within a short length of time (e.g., 2 to 5 minutes), the acquired biometric information may be output as a sound or a screen directly after the measurement is complete.

According to various embodiments of the present disclosure, in detection of biometric information that is performed a relatively long length of time (e.g., one hour or more), such as sleeping section and sleeping condition, the information detected for the corresponding length of time is stored in the electronic device 100, and then the corresponding information may be output through the electronic device 100 or transmitted to any other electronic device by the user's direct input.

FIG. 23 is a view illustrating exemplary outputting biometric information items measured by operating methods of a wearable electronic device according to various an embodiments of the present disclosure

FIG. 23 is a graph output by continuously detecting movement intensity during the user's sleeping section through the electronic device 100. According to various embodiments, it is possible not only to continuously detect and represent the movement intensity during the user's sleeping section as a graph, but also to represent the movement intensity through, for example, other types of diagram. For example, when detecting the user's sleeping section, only a specific section, such as a section where the user sleeps well or a section where the movement intensity is high, may be detected and output as a graph or only the start point and the end point of the corresponding section may be output.

As described above, in the case where the detection of biometric information is performed for a relatively long length of time like the detection of sleeping section, the continuously detected biometric information may be stored in the electronic device 100. According to various embodiments, the detected biometric information may be not only stored in the electronic device 100, but also transmitted to another electronic device, a medical institute, or a first-aid medical center.

When the acquisition and outputting of the user's biometric information are completed, in operation S321, it may be determined whether the executed application is terminated. According to the biometric information desired to acquire, the executed application may be terminated simultaneously when the acquisition and outputting of the biometric information are completed. For example, when the electronic device 100 is in a state where the user has executed the application for detecting a change in, for example, electrocardiogram so as to calculate a stress index, the executed application may be terminated when a predetermined length of time elapses after the calculated stress index is output.

According to various embodiments of the present disclosure, the user may select whether to output the acquired biometric information or whether to terminate the executed application. For example, the biometric information is detected and acquired for a relatively long length of time like the detection of sleeping section, the electronic device 100 may remain in a stand-by state until the user executes a command to output the acquired biometric information, and after the user executes the command to output the acquired biometric information, a screen, on which the user may select whether to terminate the application, may be output.

When the application is terminated according to a setting or by the user's selection, the electronic device 100 may relax the driving member 127 so that the wearing unit 102 may return to its initial state (the state where the user's body is not pressed), thereby providing a comfortable wearing feeling to the user. After the application is terminated, the acquired biometric information may be stored in the electronic device 100, or a storage medium or another electronic device accessible by the electronic device 100 to be utilized as data for the user's continuous health care.

FIG. 24 is a view illustrating one of examples of outputting biometric information measured by a method of operating the wearable electronic device, according to various embodiments of the present disclosure.

Through the electronic device 100, various types of user's biometric information may be acquired. For example, information, such as an exercise amount of, e.g., walking or running, a stress index, and sleeping section, may be acquired, and the electronic device 100 may output the acquired information individually, or output a plurality of pieces of information compositely on one screen as illustrated in FIG. 23. Whether to output individual biometric information or whether to output a plurality of pieces of information may be selected according to the user's selection.

FIG. 25 is a view illustrating a configuration of an operating module implementing a biometric signal sensing operation of a wearable electronic device according to various embodiments of the present disclosure.

FIG. 26 is a view illustrating a configuration of another operating module implementing a biometric signal sensing operation of a wearable electronic device according to various embodiments of the present disclosure.

Referring to FIGS. 25 and 26, the electronic device 100 may include a driving module 33 that adjusts the length of a wearing member, for example, the first wearing member 121 a. The driving module 33 may be controlled by a control unit of the electronic device 100 (e.g., an AP 31, a dedicated processor provided in the AP 21 or separately from the AP, or a microprocessor). According to the control of the AP 31, the driving module 33 may operate the driving member 127 mounted on the first wearing member 121 a, and according to the operation of the driving member 127, the length of the first wearing member 121 a may be adjusted. In the state where the user wears the electronic device 100, the electronic device 100, for example, the main body 101 may come in close contact with the user's body by the operation of the driving member 127.

The electronic device 100 may include a sensor that detects whether the main body 101 is sufficiently in close contact with the user's body, for example, a contact degree sensor 35 or 33 a. The contact degree sensor 35 or 33 a may be placed on one of the wearing member (e.g., the wearing member 121 a) and the driving module 33. In addition, although not illustrated, the contact degree sensor 35 or 33 a may be disposed adjacent to the main body 101, for example, the biometric signal sensor 113, or a location where they may be in contact with the user's body, such as the binding member 123.

When the contact degree sensor 35 is provided on the first wearing member 121 a, the contact degree sensor 35 may detect the contact degree of the main body (e.g., the main body 101) in relation to the user's body by detecting, for example, the pressure pressing the user's body, and the user's body heat. The contact degree sensor 35 may include an optical sensor. For example, as the main body 101 is in close contact with the user's body, the amount of light detected through the optical sensor may be reduced, which allows the contact degree between the main body and the user's body to be detected.

When the contact degree sensor 33 a is provided on the driving module 33, the contact degree sensor 33 a may indirectly detect the contact degree between the main body and the user's body. For example, as the contact degree between the main body and the user's body increases, the electric power required for driving the driving member 127 (e.g., current or voltage) or an electric resistance may increase. From this, the contact degree sensor 33 a may calculate the contact degree between the main body and the user's body.

The driving module 33 may activate the contact degree sensor 35 or 33 a simultaneously with operating the driving member 127, and the contact degree sensor 35 or 33 a may detect the contact degree between the main body and the user's body and transmit the detected contact degree to the driving module 33 and the AP 31.

The electronic device 100 may further include a sensor driving module 37 that controls the biometric signal sensor 113, and a sensor driving module 37 may controlled by the AP 31. When it is determined that the main body and the user's body are sufficiently in close contact with each other, the AP 31 or the driving module 33 provides the information to the sensor driving module 37, and the sensor driving module 37 may activate the biometric signal sensor 113. According to an executed application, the activated biometric signal sensor 113 may detect biometric signal information required for the application and provide the detected biometric signal information to the AP 31 through the sensor driving module 37.

The above-described operating methods S100, S200, and S300 of the wearable electronic device may be performed by the operating module 30 as described above. The method of adjusting the length of a wearing unit (e.g., first wearing member 121 a) as described above in the above-described operating methods S100, S200, and S300 may be controlled by the driving module 33. Hereinafter, a method of adjusting a length of a wearing unit will be described with reference to FIGS. 27 and 28.

FIG. 27 is a flowchart illustrating a method of adjusting a length of a wearing unit of a wearable electronic device according to various embodiments of the present disclosure.

FIG. 28 is a flowchart illustrating another method of adjusting a length of a wearing unit of a wearable electronic device according to various embodiments of the present disclosure.

Referring to FIGS. 27 and 28, in describing the methods of adjusting a length of a wearing unit 8, reference will be made to operation S115 among operations of tightening a band S115, S213, and S315 as described above. However, it is noted that according to various embodiments of the present disclosure, the method of adjusting a length of a wearing unit is not limited thereto, and operation S213 or operation S315 may also be executed through the methods illustrated in FIGS. 27 and 28 or through various modified methods.

As discussed above with the operating methods S100, S200, and S300, operation S115 may be executed periodically depending on an executed application.

According to various embodiments of the related art, under a predetermined condition, for example, when it is determined that the movement of the user who wears the electronic device becomes active (e.g., sensing excise in operation S211) or an application is executed by the user's input (e.g., operation S313), operation S115 may be performed.

Referring to FIG. 27, for example, an application for detecting a biometric signal is executed, the driving module 33 may be controlled by the AP 31 so as to determine first whether the main body 101 of the electronic device 100 is in close contact with the user's body in operation S115-1. Whether the main body 101 of the electronic device 100 is in close contact with the user's body may be determined based on the data detected from the contact degree sensor 35 or 33 a. When the main body 101 is not sufficiently in contact with the user's body, the driving module 33 may operate the driving member 127 in operation S115-2 so as to contract the wearing member (e.g., the first wearing member 121 a). The driving module 33 may continuously detect the contact degree between the main body 101 and the user's body while contracting the wearing member so as to maintain or repeat the operation of the driving member 127.

As the wearing member is contracted, the main body 101 gradually comes in close contact with the user's body, and the contact degree sensor 35 or 33 a may detect whether the main body 101 and the user's body is brought sufficiently in close contact with each other. Here, “sufficiently in close contact” means that the biometric signal sensors 113 are in close contact with the user's body such that the user's biometric signals may be sufficiently detected, in which the contact degree may be previously set in the process of manufacturing a real product and may be input to and stored in the electronic device 100, for example, the driving module 33. When the main body 101 and the user's body are sufficiently in contact with each other, the driving module 33 may transmit the corresponding information to the AP 31 or the sensor driving module 37.

When the information indicating that the main body 101 and the user's body are sufficiently in close contact with each other is received from the AP 31 or the driving module 33, the sensor driving module 37 may activate the biometric signal sensors 113. For example, the sensor driving module 37 may perform operation S117 and S215 (biometric information acquisition/display) or operation S317 (biometric information acquisition) and operation S319 (biometric information output) of the above-described operating methods S100, S200, and S300.

Referring to FIG. 28, the method of adjusting a length of a wearing unit (e.g., operation S115) may further include an operation of fixing the driving member 127 in operation S115-3. Operation S115-3 is an operation of fixing the driving member 127 when the state, in which the main body 101 is sufficiently in close contact with the user's body, is determined, so that the length of the wearing member (e.g., the first wearing member 121 a) may be maintained. For example, in order to maintain the state where the main body 101 is in close contact with the user's body, the electronic device 100 may press the user's body with a predetermined magnitude of force. The driving member 127 may also receive load acting in the direction of extending the length of the wearing member by the force pressing the user's boy. By fixing the driving member 127, operation S115-3 may prevent the length of the wearing member from being extended by the load applied to the driving member 127, and maintain the state where the main body 101 is in close contact with the user's body.

In the state where the fixing member 127 is fixed in operation S115-3 so that the main body 101 is brought into close contact with the user's body, the driving module may transmit the corresponding information to the AP 31 or the sensor driving module 37, and the sensor driving module 37 may activate the biometric signal sensors 113.
